Dredging Complete In Popponesset Bay Approach Channel

Posted on April 15, 2024

The Barnstable County dredge program finished dredging the Popponesset Bay approach channel on March 28, according to a notice posted to the town website on Wednesday, April 10.

Most of the dredging took place in the northern section of the channel, the notice said, and the areas that needed dredging were significantly reduced this spring since the channel was dredged in October.

The controlled depth of the channel remains at five feet at mean low water, but shoals shift and shallower depths may be found throughout the channel limits. Once completed, a post-dredge survey plot will be made available and distributed as an aid to mariners navigating the channel.

One section of roughly 1,200 feet of dredge pipe is anchored off the Popponesset Spit, submerged and marked with yellow floats along its length. Boaters are advised to exercise caution when navigating that area.

The northern, middle and southern sections of the pipe are marked at the following coordinates:

N 41o 34.902’ / W070 27.040’

N 41o 35.112’ / W070 26.947’

N 41o 35.013’ / W070 27.029’

The layout of the pipe is approximate, and the pipe may move from its present location during periods of strong winds or seas.
